Certified Lean Six Sigma Black Belt (CLSSBB) Practice Exam

A Certified Lean Six Sigma Black Belt from the Council for Six Sigma Certification (CSSC) is someone who have a comprehensive grasp of the entire Six Sigma Body of Knowledge. Furthermore, they exhibit a deep understanding of the philosophies, principles, supporting systems, and tools inherent in Six Sigma.

The Black Belt Certification also signifies proficiency in team leadership, understanding team dynamics, and the adeptness to assign roles and responsibilities effectively within a team. Moreover, this individual demonstrates an understanding of the DMAIC model aligned with Six Sigma principles, a fundamental grasp of lean enterprise concepts, and the capability to swiftly identify activities that do not add value.

The Council for Sigma Certification (CSSC) provides two different paths for achieving a Lean Six Sigma Black Belt Certification. Those who have undergone prior training and believe they possess a substantial understanding of the topics covered in the Black Belt Certification "Body of Knowledge" can opt to take our standard comprehensive examination.

Alternatively, individuals utilizing one of our complimentary Self-Study Guides, either independently or in collaboration with a training provider, can take multiple short exams as they advance through various sections, rather than a single extensive exam.

Moreover, those pursuing the second certification option would have the opportunity to acquire the different levels of our standard certifications (White Belt, Yellow Belt, Green Belt, and Black Belt) as they progress through their certification journey, without incurring any additional examination fees.

Certification Requirements:

To attain the esteemed title of a CSSC Certified Lean Six Sigma Black Belt (CSSC-CLSSBB) conferred by The Council for Six Sigma Certification, individuals must satisfactorily complete CSSC Lean Six Sigma Black Belt Certification Exam.

There are no prerequisites for undertaking the CSSC Lean Six Sigma Black Belt Certification Exam. Upon payment of the examination assessment fee, candidates will have a one-year window to successfully pass the exam.

Unlike other certifications, there is no project requirement for this Certification. However, it serves as a mandatory prerequisite for individuals aspiring to pursue our Level II Black Belt Certification, which does entail a project requirement.

• Customer Requirements (VOC): Understanding what the customer values and translate those into measurable requirements.

Topic 2: Measure Phase

• Data Collection and Measurement Systems Analysis (MSA): Gathering relevant data to understand the current state of the process and assess the measurement system's accuracy and capability.
• Process Mapping: Creating a visual representation of the process steps involved.

Topic 3: Analyze Phase

• Root Cause Analysis (RCA): Identifying the root causes of defects and variations using tools like cause-and-effect diagrams (Ishikawa diagrams) and Five Whys.
• Statistical Analysis: Applying statistical tools like descriptive statistics, hypothesis testing, and correlation analysis to understand data patterns and relationships.

Topic 4: Improve Phase

• Process Design and Improvement: Developing solutions to eliminate defects and inefficiencies based on root cause analysis. This may involve implementing Lean tools like 5S, Kanban, and Poka-Yoke.
• Design of Experiments (DOE): Testing and validating the effectiveness of potential solutions through experimentation.

Topic 5: Control Phase

• Implementation Planning and Control: Developing a plan to implement the chosen solution, monitoring its effectiveness, and establishing control mechanisms to sustain the improvements.
• Statistical Process Control (SPC): Using control charts to monitor process performance and identify any deviations requiring corrective action.
